To all whomfitfi'nay concern: Beitv known-that I, VAILTER S. Ence, a. citizen ef the United' States, and a resident of New' `York city, in the'county of New York and State of NewI York, have invented certain new and useful Improvements in Dani Constructions, of which the following is a specification.

' My invention relates to dainconstruetions, and the object of my invention is to provide an improved constructioninV which concrete is used and reinforced by metal rods in such i a manner as to brace and strengthen the whereby the expansion and contraction of the structure as a. whole, will not cause the deck of thedam to crack, by reason of uneven 'expansion between the concrete and reinforcing rods.

A further object is to yprovide exceptiony' ally strong' joints between the buttre'sses and sidewalls and to provide at these junctions, pillarconstructions which extend from the base of the (lain to thedeck, and Where thought to be necessary, to' strengthenthese pillar portions with metal reinforcement.

The deck may be supported by thev but.; tresses and walls, or maybe formed integral, vdepending on local conditions and the spe-- ciiic plans furnished by the engineer, in charge of the work.-

AIn the drawings which form a part o this' specification,` the deck is shown as formed integral with the walls'andbut- -tresses v Referring to said drawings, Figure 1 is a cross sectional view through a. dam einbodvl i'n'g my invention. with portions of thewall broken away to disclose certain features'of constru'etion. Fig; Q is a plan view of. av .portion of the dam. Fig. 3 is a rear. View of a'portion of the dam, Fig. 4 is a. sectional View through a portion of the deck to illustrate 'the location of the reinforcing rods.

,. Fig. '15 is a view of a ,portion of the .deck/fo further illustrate the arnangement of the reinfotciiig rods embedded therein, itfbeiiig un- Ailerstood-that the rods are shown as exposed 'crete at the junction 11, and corbels 18 atrthezjunction ot vthe deck vand walls 14, each of which extendl troni 4forthe purpose of clearness only. -Fig. is' a plan View of the walls and buttresses with the pillars/formed integral, and all of samereinforced by metal portions, the deck being removed.

The dani consists primarily of an inclined upstream deck l0 supported by vertical walls l1l running parallel to the stream, and inclined walls or buttresses llel1 and 11a extending across the stream and the walls and buttressesjoined integrally where they cross each other. By this arrangement-a series of rectangular walls are provided, on the tops of which the deck 10 is supported.A It will therefore be seen thatlthe deck may be divided up intorectangular slab-like sec-' tions, the ends .of each section extending half-way `across the' thickness of each wall, so that-fthe weight of water being known which the deck and walls-must support, the thickness and strength of the Adeck and walls mayy be easily ascertained. `Each Section may be formed with `expansion joints in which the reinforcing rods extend from wall 4to wall only, as illustrated in Fig. 5, and series of rods 12 and .13, crossing each other and placed nearer together near the middle of the walls lthan they are spaced adjacent thereto, to more perfectlyfcarry the load, as will be readily'. understood. -By this arrangement each section` becomes 'a unitconstruction and the thickness of the deck and the reinforcement may he varied at different portions 'of the structure to most perfectly carrythe load and resist 'the strains set up. If desired, each section of' the deck may be cast. separately and laid in position and secured to the Walls in any proper manner.

The inclined walls or buttresses 14 which extend across the stream are reinforced in those cases where the dam issifficiently'high to need reinforcing, by rods '15 which may extend 'from wall to'wall as illustrated in Fig. 3, or may extend unbroken across the stream if preferred, entirely embedded in the said walls.- The walls 11. running parallel to the stream may also be reinforced by the Arods 1G, which extend from wall Ito wall, or continuously the entire length there! of, ,as desired. .To further strengthen t-hc construction. corbels 1i' are formed vof con-1 'if the deck and walls Wall to wall, as will be readily understood.

of ythe deck, tlie water,

' buttresses which extend with,

n liigli temperatures, or otherwise Where cement can be saved by reinforcing or Where great strength is required, pillars 18 are constructed integralvitli the Walls, by forming fillets 19, which extend from top to bottoni oii the walls, and thus permit of tlie Walls being made of less thickness, since the fillets serve to stilien tlie construction. In cases -Where greater strength is needed, these pildani, falls first on the npper side ot tliis Wall and flows down over same, t-lins preventing noise and the ground from being Washed away to e certain degree, byA the Water,

The dein may be floor when built on a poor icundation, but in the vpresent drawings the buttresses are shown as resting in trenclics'in die4 groen Openings may be provided 'from cell te` cell throughv tlie supporting wells through Wliicli entrance 'can be made tor purposes et inspection, and to permit the escape oi Water in caseof e. leali in the decir. The cells formed between the walls ina-y be filled Witli loose rock or earth wli'ere saine is plentiful and can be obtainedata lowcost, thus giv ing.,-` greater Weigl'it to tbe construction ind permitting the walls to be built Wit'n less concrete, thereby reducing tbe cost ot ccnstruction.

By the' construction oit a dani es above specified the dain may be built et a low cost and oi" great strength end durability.
